Expert repair and recalibration of Avtron load cells and precision instrumentation for Indian industry.
AVTRON Product Lines We Repair
Our engineers are trained on the full AVTRON product range. Below are the major product families we service.
Load Cell Series (Compression, Tension, Shear, Bending Moment)
Avtron's core precision load cells for static and dynamic force measurement in weighing systems, testing equipment, and process control. Common issues include solder joint fractures in wheatstone bridge circuits, cable shielding degradation, and creep drift over time due to temperature cycling in Indian manufacturing environments.
Rotary Encoder Series (Incremental and Absolute)
Avtron encoders for shaft position feedback, speed measurement, and motion control in industrial drives and machinery. Repair focus includes optical sensor contamination, bearing wear, cable connector corrosion, and firmware re-initialization on absolute encoders losing position data after power loss.
Strain Gauge Amplifiers and Signal Conditioners
Avtron signal conditioning modules for amplifying 4-20mA outputs from load cells and strain gauges. Common failures include op-amp failure, precision resistor drift, 24VDC power supply failure, and analog-to-digital conversion errors causing erratic readings in cement and steel plant weighing systems.
Pressure Transducers and Transmitters
Avtron hydraulic and pneumatic pressure measurement instruments for industrial automation and machine tool control. Issues include diaphragm rupture under overpressure, electrical connector water ingress (common in wet Indian mining and heavy equipment environments), and zero-offset drift requiring recalibration.
Temperature Compensated Load Cells and Transducers
Avtron temperature-compensated instruments with internal RTD or thermistor for stable measurement across -20C to +70C operating range. Repair requires understanding of thermal bridge compensation circuits and recalibration procedures to restore temperature-span accuracy in Indian foundries and outdoor heavy equipment applications.

Common AVTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AVTRON equipment arriving at our workshop.
- ✓Load cell wheatstone bridge solder joint fracture — Vibration-induced fatigue in steel mills and cement plants, thermal cycling stress from 50C+ temperature swings. Avtron load cells in open Indian foundries experience repeated thermal shock causing cold solder joints at bridge resistor connections.
- ✓Encoder optical sensor degradation and counting errors — Dust, cement powder, or metal fines accumulation on Avtron encoder optical windows in Indian mining and cement environments. Contaminated photo-diode reduces signal-to-noise ratio, causing missed pulses and position loss in rotational feedback circuits.
- ✓4-20mA transmitter output stuck or non-linear — Avtron amplifier precision resistor drift (metal film resistors aging under 40-50C ambient heat in Indian factories), or op-amp rail saturation due to power supply noise on shared 24VDC lines in heavy machinery control cabinets.
- ✓Pressure transducer zero-offset shift and erratic readings — Avtron diaphragm mechanical creep under sustained load, or temperature compensation circuit failure. Common in Indian steel rolling mills where pressure sensors experience continuous 50+ bar fluctuations and 60C ambient temperatures, causing bridge imbalance and temperature coefficient drift.
- ✓Rotary encoder absolute position loss after power cycle — Avtron multi-turn absolute encoder battery backup failure (internal coin cell depleted after 5-7 years), or non-volatile memory corruption from power surges on encoder cable shield in Indian installations with poor grounding practices.
- ✓Load cell cable connector corrosion and intermittent connection — Avtron connector pin oxidation common in humid Indian coastal areas and high-moisture environments (sugar mills, food processing). Salt spray or hygroscopic cement dust corrodes gold-plated contacts, causing high resistance and noise in signal path.

Frequently Asked Questions — AVTRON Repairs
Do you repair Avtron equipment anywhere in India?+
Yes. Synchronics repairs the full Avtron product range — load cells, rotary encoders, strain gauge amplifiers, pressure transducers, and signal conditioners. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. Our Vadodara, Gujarat facility houses specialized test benches for pressure, temperature, and dynamic load cell calibration.
Can you recalibrate and issue NABET/ISO traceable certificates for Avtron load cells?+
Yes. Synchronics is equipped with NABET-accredited weight standards, precision pressure calibrators, and multi-point load testing fixtures. We recalibrate Avtron load cells across the full range (typically 5, 20, 50, 75, 100% points), measure temperature coefficient, and issue detailed NABET/ISO 9001 calibration certificates with uncertainty statements. Turn-around is 7-10 working days from receipt in Vadodara.
How long do Avtron repairs typically take and what is your warranty?+
Standard Avtron load cell, encoder, and transmitter repairs take 5-7 working days. Urgent repairs can be expedited to 2-3 days for additional fee. We issue 12 months warranty on all repairs covering parts and labor. If a repaired Avtron sensor fails within warranty, we replace it at no cost or repair it again free of charge. We maintain a ready stock of Avtron modules for quick swap-outs.
What is the difference between Avtron absolute and incremental encoders, and which should I use?+
Avtron incremental encoders (HTL or SSI output) are cost-effective for continuous speed/position feedback but lose position on power loss. Absolute encoders retain multi-turn position memory after shutdown — essential for Indian heavy equipment and crane/hoist applications where startup position must be known. Choose absolute if your system cannot home on startup; choose incremental if cost is critical and homing is available. Synchronics repairs both types and advises on upgrade paths.
My Avtron load cell reads correctly cold but drifts 5-10% when the foundry temperature rises to 50C. What is wrong?+
Avtron load cells have temperature compensation built-in, but the compensation circuit (thermistor-based bridge) can drift or uncompensated load cells can be installed. If temperature coefficient exceeds 0.05% per degree C, the bridge balance is likely off. Synchronics measures your cell's actual TCAL (temperature calibration factor), re-trims the compensation resistors or bridge circuit, tests across a 0-60C range in our chamber, and restores accuracy to within specification.
How do I send my AVTRON unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AVTRON drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AVTRON repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AVTRON unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
